	\subsection{Compiling and running}
	
		To compile our program, \textit{Javac} is needed and must be in your \textit{PATH} environment variable.\\
        Open a shell and go in the directory where source folder (\textit{src}) is located.         
        Then execute the following command line :
        \begin{verbatim}
           ./mapper <server_url> <x1> <y1> <x2> <y2>
        \end{verbatim}
        
        The \verb?mapper? script will compile and then run the program with the given arguments. 
      
      	\textbf{Arguments :}
      	\begin{itemize}
      		\item server\_url : the url of lokkaria server with its port number
      		\item x1 : x coordinate of the lower left point
      		\item y1 : y coordinate of the lower left point
      		\item x2 : x coordinate of the upper right point
